Circuit Operation

The throttle position sensor signal and idle position signal are sent to the auto-cruise control-ECU through this circuit.

The throttle position sensor sends a voltage signal to terminal 1 of the auto-cruise control-ECU. The voltage depends on throttle opening angle.

The auto-cruise control-ECU receives an idle position signal from the ECM < M/T> or PCM < A/T> at terminal 2. The signal is OFF when the accelerator pedal is depressed, and ON when the accelerator pedal is released.
